TECHNICAL FIELD

The invention relates to controllers for controlling the play ofcomputerised games, more particularly but not exclusively, the inventionrelates to an actuator system of a game controller for a gaming console.

BACKGROUND

There are many different types of gaming consoles currently availablefor operating a video game. For example, Microsoft®, Sony® and Nintendo®manufacture the Xbox®, Playstation® and Wii® gaming consoles,respectively. The gaming consoles typically include a game controller sothat a user can control the operation of the video game.

Some known game controllers include a form of actuator system for theoperation of control of the functions of the video games. Actuators,buttons or other depressible or manually operable devices are typicallyused for controlling discrete actions such as the firing of a weapon oran attack command. It is known to provide a button or actuator which isintended to be operable by the index finger of a user; such buttons arecommonly known as triggers.

At times, dependent upon the video game being played, it can benecessary to depress the trigger a distance before the triggerinitiation point is reached and the command actually acknowledged. Thisrenders part of the depressing action futile. Likewise, after thecommand has been operated, it is often possible to carry out furtherdepression of the trigger past the trigger initiation point. Thisfurther depression is unnecessary and may also be disadvantageous.

Furthermore, in other situations in some video games, the strength of acommand is increased or decreased dependent upon how frequently thetrigger is depressed. As such, depressing the trigger the whole distanceis unnecessary and excessive for the command or operation required.

It is desirable to have a controller, particularly for gamingapplications, that is more responsive or has less scope for allowingunnecessary over-movement by the user of the controller.

Due to the rapidly expanding gaming market and development of involvedgames invoking considerable player input, it is desirable for players tobe able to customise their controllers in order to gain increasedcontrol in a variety of gaming circumstances.

The present invention seeks to improve upon or at least mitigate some ofthe problems associated with controllers of the prior art by providing agame controller, which includes an adjustable trigger system that has amechanism to allow the end user to control or recalibrate the maximumand/or minimum trigger positions.

Detailed descriptions of specific embodiments of the game controller andits trigger mechanisms are disclosed herein. It will be understood thatthe disclosed embodiments are merely examples of the way in whichcertain aspects of the invention can be implemented and do not representan exhaustive list of all of the ways the invention may be embodied.Indeed, it will be understood that the game controller and its triggermechanisms described herein may be embodied in various and alternativeforms. The figures are not necessarily to scale and some features may beexaggerated or minimised to show details of particular components.Well-known components, materials or methods are not necessarilydescribed in great detail in order to avoid obscuring the presentdisclosure. Any specific structural and functional details disclosedherein are not to be interpreted as limiting, but merely as a basis forthe claims and as a representative basis for teaching one skilled in theart to variously employ the invention.

FIG. 1 is exemplary of a game controller 100 in which the presentinvention could be employed. The game controller 100 includes a bumpercontrol function 102, button control functions 104, analogue joystickcontrols 106, and a trigger body 108. FIG. 1 illustrates the positionsof the trigger body 108 in relation to the position of theaforementioned features of the game controller 100.

FIG. 2 is a cut-away view of part of the game controller 100illustrating an adjustable trigger mechanism according to a firstembodiment of the invention. The game controller 100 also includes acontroller chassis 110, which encloses its internal components. Thetrigger body 108 can extend at least partially through an opening in thecontroller chassis 110. Referring now also to FIGS. 3-8, the gamecontroller 100 also includes:

a printed circuit board (PCB) 112;

a trigger mechanism chassis 114 fixed to the PCB 112;

an adjustment strike plate 116 integral to the trigger body 108;

a first trigger adjustment control screw 118 for adjustment of triggerdepression;

a second trigger adjustment control screw 120 for adjustment of thetrigger command initiation point;

a threaded insert or screw thread 122 cut into the controller chassis110;

a trigger pivot bearing 124 integrally formed with the trigger mechanismchassis;

a trigger sensor link arm 126; and

a trigger motion sensor 128.

FIG. 3 is an enlarged section of FIG. 2 showing in more detail thetrigger adjustment mechanism in accordance with the invention.

FIG. 4 is a cross sectional view of the trigger mechanism. In thisembodiment the trigger mechanism has two trigger adjustment controlscrews 118, 120; first trigger adjustment control screw 118 foradjustment of trigger depression, and second trigger adjustment controlscrew 120 for adjustment of trigger command initiation point as shown inFIG. 2 respectively.

In this embodiment the first and second trigger adjustment controlscrews 118 and 120 that are used are grub screws but could be manydifferent threaded mechanisms.

In this embodiment the screw thread 122 for receiving the screwmechanisms is cut into the chassis 110 of the game controller 100 asshown in FIGS. 2 and 3, respectively. In other embodiments, it would bepossible to use threaded inserts with nylon locking systems or entireadjustment mechanisms 130, 132 fitted as a complete component that couldbe inserted through an aperture in the controller chassis 110 in suchembodiment it is envisaged that the user may be able to adjust thetrigger settings without the use of a tool, for example by providing agrip coupled to the screw thread, preferably this would be integral withthe screw thread as shown in FIGS. 7 and 8.

In some embodiments, the position of the trigger body 108 would beadjusted by use of a specified tool that would be provided to turn thefirst and second trigger adjustment control screws 118 and 120, whichare located next to the trigger body 108, on the controller chassis 110.

One advantage of the present invention is that it allows adjustments tobe made to the trigger response; such adjustment could be customised tosuit the nature of the video game that is in use at the time ofoperation and the skill of the operator. For example, in combat stylegames involving a shooting function it is often the case that thetrigger would need to be depressed a certain amount before any commandwas prompted. The second trigger adjustment control screw 120 can beadjusted so that the command was prompted with any amount of depressionof the trigger body 108, by using the required tool (for example anAllen key, or hex or star driver, cross head or flat head screwdriver,spanner or wrench) to turn the second trigger adjustment control screw120, whereby driving it into or out of the controller chassis 110 byvirtue of the threaded insert or screw thread located within controllerchassis 110.

After reaching or passing the command initiation point no furthercommands are given from the trigger sensor link arm 126 to the triggermotion sensor 128; therefore the first trigger adjustment control screw118 which controls the degree of trigger depression allows the operatorto restrict the amount of travel available to the trigger body 108, asthey desire. The first trigger adjustment control screw 118 would impedethe movement by striking the adjustment strike plates, which arepreferably formed integrally with the trigger body 108, which triggerbody 108 is pivotally mounted preferably on a trigger pivot bearingwhich may also be integral to trigger mechanism chassis 124.

Such an adjustment would directly relate to the majority of combat stylegames or other varieties of firing operations in video games.

The present invention could find application in a variety of other videogames genres but for the simplicity of this disclosure reference is madeto combat style games.

A further advantage of the present invention is that it minimises theamount of motion an operators finger must travel, therefore minimisingthe recovery time after trigger initiation contacts have been madeallowing the operator to commence command prompt again and again morerapidly, or to operate different commands quicker. As the movement thatis required to operate commands detected by the trigger motion sensor128, by depressing the trigger body 108, the risks of any relatedrepetitive strain injury acquired due to the repeated movement of thefinger when operating the trigger function would be greatly reduced. Inknown controllers the operator may be require to move their finger 11 mmwhereas in the present invention adjustment of the first triggeradjustment control screw 118 and the second trigger adjustment controlscrew 120 allow the operator to reduce the required movement of theirfinger to 5 mm thus reducing the overall motion required by the operatorby over 50% of the initial movement required, whereby providing a healthbenefit to users retaining healthy joints after many years of vigorousgaming. Repetitive strain injury is a clinically proven medical issuerelated to hours of repeated movements made during activities like themovements made while depressing the trigger function of the controller.

In other video game genres, such as driving games, trigger responsecould be controlled by adjustment of the first trigger adjustmentcontrol screw 118 and the second trigger adjustment control screw 120 toallow the operator greater control over breaking and acceleratingfunctions of the game, for example restricting maximum throttle settingsand breaking level settings for difficult corners. This could beadjusted by assessing where the greatest advantageous breaking oraccelerating position would be, and then recreating this position withthe trigger adjustment control screw for adjustment of triggerdepression 118.

In this application the degree of the trigger body 108 depression isdetected by trigger motion sensor 128 which are coupled together by thetrigger sensor link arm 126. The degree of depression of the triggerbody 108 is converted into a signal which signal directly relates to acommand to be executed by the video game for example the amount ofacceleration or braking to be applied. The trigger motion sensor 128 isconnected to the trigger mechanism chassis 114 coupled to the printedcircuit board 112. The present invention provides a device to restrictthe range of movement of the trigger body 108 which the trigger motionsensor 128 is effectively able to detect, and thus limit the magnitudeof the command which can be made by the operator when depressingtrigger. A further advantage of this embodiment is that the ergonomicdesign of the controller is not compromised.

FIG. 6 depicts the use of a stopping block 134 for control of triggerdepression, this could be achieved by insertion into the base of thetrigger of a screw comprising screw head which interacts with controllerchassis 110. This system could be used instead of the trigger adjustmentcontrol screw 118 for adjustment of trigger depression. This system mayincorporate a stopping block of the desired shape and size to preventthe trigger from depressing fully and this would be attached via a screwfixing into a threaded portion of the trigger body 108, or by any othermeans of mechanical fixing such as those that would be apparent to thoseskilled in the art. The stopping block 134 could be interchangeable withstopping blocks or different dimensions depending on the intendedapplication and the degree to which movement of the trigger is to berestricted. The screw head itself may be shaped such that the angularorientation of the screw with respect to the controller chassis 110determines the degree of trigger movement, for example the outer surfaceof the screw head could be any noncircular shape such as oval or spiralshape, wherein the radial dimension of the screw head is not constant.In such embodiment is envisaged that trigger adjustment control screw120 may also be employed in order to provide adjustment of triggercommand initiation point to achieve fully adjustable trigger commands.

It can be appreciated that various changes may be made within the scopeof the various embodiments of present invention, for example, the sizeand shape of the features may be adjusted. In other embodiments of theinvention it is envisaged that a system could incorporate several buttonor slider controls on the external case of the controller which may beadjusted to select pre-set ranges of movement, or pre-set triggerdepression or preset trigger initiation command points. Each of thesecould be pre-set in manufacture or by the operator to correspond topopular video games or specifically chosen video games that the operatorhas chosen for maximum efficiency. It is also envisaged this inventioncould be used for other buttons provided on the controller. It isenvisaged the invention could be employed with digital sensors orswitches which generate digital signals having an on state and an offstate since such switches typically require a predetermined range ofmovement to change states such that required range of movement to changestates can be reduced. It is also envisaged this invention could beincorporated to adjust the button depression depth required of suchdigital switches to its greatest point before such a command for thefunction it controls would be given.

In some embodiments the first trigger adjustment control screws 118 andthe second trigger adjustment control screw 120 can be entirely releasedrestoring the full range of trigger movement.
